FiiO M9 Portable High-Res Lossless Music Player

A player that does it all

When developing the M9, we at FiiO saw that there wasn't any one player that combined all of the functions people want. Was there a player that could transmit the HWA/aptX/aptX HD/LDAC lossless Bluetooth codecs, even when used as a USB DAC? What about something that also contained a highly optimized audio circuit for excellent sound quality? Did any players also give the user an experience worthy of a flagship, capable of many features including Wi-Fi music streaming all in a slick interface? We sought to change that with the M9 – which does all of this and more.

As a Bluetooth transmitter: LDAC/aptX/aptX HD/SBC (both natively from the player and through USB DAC)

As a Bluetooth receiver: Functionality to be added with software updates

Dual AK4490EN DACs for superb decoding performance

The two AK4490EN DACs employed in the M9 feature a high signal-to-noise ratio, exceptional dynamic range, and low distortion – making for a precise yet exciting sound signature.

Built-in dedicated FPGA with DSD128 hardware decoding

Inside the M9 is a high-performance A3P030 FPGA, responsible for ensuring your music (whatever sample rate) is played back accurately by stabilizing digital clock signals. The FPGA also decodes DSD64/128 in hardware, which the M9 supports in ISO/DFF/DSF formats.

Eight-layer HDI PCB ensures excellent sound quality

For the first time, in the M9 FiiO uses an eight-layer HDI (High Density Interconnect) PCB with a thickness of only 0.08mm. While the M9 PCB is more complex than the one in the M7, it also allows more components to be integrated into a smaller space, leading to a smaller PCB and a smaller device overall. Combined with the fact that the M9 PCB is L-shaped, similar to modern smartphones, and you have a recipe for outstanding sound quality.

The TI OPA1612 is used as the LPF, while the TI OPA1622 serves as the current buffer. To achieve single-ended and balanced output, there are two OPA1622 op-amps used that provide up to 77mW* of power under a 300Ω load.

Get your music from wherever and whenever

With the M9, you can get your music from wherever, whenever. Don't want to deal with wires when transferring your songs over? Use Wi-Fi on the M9. Want to listen to your music on your computer? Do so with DLNA without having to worry about space on the M9. Want to discover new music on streaming services? The built-in streaming apps have you covered.

*Can install whitelisted third-party music streaming apps

Always your faithful companion

Under normal usage the M9 can last around 10 hours, while in deep sleep (standby) mode the M9 can be still be used after a whopping 45 days! And being in deep sleep mode does not mean sacrificing convenience – just hit the power button, and the M9 instantly is ready to go.

45 days - Deep sleep

Indulge in the pleasure of balanced

The M9 contains both single-ended 3.5mm and balanced 2.5mm audio jacks, for even more ways to listen with your headphones. The M9 also supports in-line controls in both CTIA (common with Android headsets) and iOS headsets. (With iOS headsets, only play/pause functionality is supported.)

A picture is worth a thousand words

Unique to the FiiO M9 is RGB light indicator status that shows what audio format you are listening to! Instantly know what audio format your M9 is playing as well as its overall status, with the indicator status showing red to remind you to charge your device.

Bring out the best in your computer with USB DAC functionality

The M9 can be used as an asynchronous USB DAC with both Macs and Windows PCs. With Mac computers, you can just plug-and-play the M9 with no drivers needed. With Windows PCs, a simple install of drivers by FiiO is needed. The M9 can also act as your computer's Bluetooth transmitter – simply hook the M9 up to your computer as a USB DAC, and then have the player transmit Bluetooth audio to your headset!

USB audio and optical out support

The M9 supports USB audio out (send digital audio bits through USB), with even support for DoP/D2P. Also, the M9 is one of the few players that can receive Bluetooth audio and output it through optical (SPDIF) out.

*You can select between USB Audio DoP/D2P in the settings menu*Bluetooth receiving functionality will be added with software updates

Incredibly fast with a deeply customized OS

In the heart of the M9 lies the Android operating system, deeply customized by FiiO. This allows you to navigate through menus at an astonishing speed and with amazing ease due to the carefully thought out customized user interface.

Also, apps for popular streaming services including NetEase Cloud Music, MOOV, Tidal and KKBOXS are pre-installed to allow even more ways to listen to music.

The all-aluminum body tastefully combines both straight and rounded edges in an unmistakably unique design, with the gentle curve of the left side naturally transitioning to the bold straight lines of the right side. Despite its beautiful form, the M9 doesn't sacrifice functionality – the volume wheel has been upgraded for more accurate control and a better, more tactile feel; while the power, play/pause, and change tracks buttons on the left have been arranged for even greater comfort in using the player.

LG IPS touchscreen with in-cell technology

Adorning the front of the M9 is a vibrant, clear 3.2 inch IPS screen capable of 16 million colors and supporting 5-point touch. This IPS screen allows you to easily operate your device with its ability to show even the finest of details.

Contemporary USB Type-C connector

The M9 utilizes the modern USB Type-C connector, which allows it to not only be used as a USB DAC but also allows output of digital audio signals to other devices through USB. Of course, USB Type-C also enables charging and file management on the M9 when connected to other devices.

Be accepting of all music with 2TB of storage

The M9 comes with a healthy 2GB of storage, but the storage can be expanded up to a massive 2TB with micro-SD cards!

Hi-Res Audio certified

The M9 has been certified by the Japan Audio Society to be “Hi-Res Audio” worthy, only achieved by devices truly capable of bringing a realistic and natural audio experience.

Wealth of accessories fit for a king

Every M9 comes with a TPU case, high quality USB cable, and a tempered glass screen protector. An optional PU leather case is also available.
